So you've got a lot of drums that need outdoor spill containment? You could buy a bunch of our Ultra-Hard Top P4s. We'd be more than happy to sell them to you. But if you won't have a need for multiple locations and all of your drums will be stored in the same location, then the Ultra-Hard Top Plus Models could be the perfect fit for you.
These units provide one large, covered, spill containment storage area for as many drums as you have space for (we have part numbers for systems up to 20 drums but you can use the extender kits to make them as large as you need).
